"""Step 3 tests — non-tautological top-K retrieval + REAL-SessionContext two-arg injection.
The true match shares the *structured* similarity fields with the query but uses different
description text; the decoys share surface text but differ structurally. The injection test
uses a REAL ``agent_framework.SessionContext`` (not a single-arg fake), exercising the
genuine two-arg ``extend_instructions(source_id, instructions)`` GA signature — retiring the
Critical Fase 1 risk. Pattern: tests/spikes/test_d_verdictstore.py + real SessionContext.
